  1. Includes 18,852 shares of Class A Common Stock subject to restricted stock units and performance stock units that remain subject to vesting. Represent stock options to purchase shares of the Issuer's Class A Common Stock ("Options") granted on July 29, 2025. The Options are a commitment by the grantee to exercise a predetermined number of Options every quarter for eight quarters (the "Committed Options") at an exercise price per share equal to $10,00, which reflects the fair market value of a share of Class A Common Stock on the grant date. If the reporting person does not exercise the Committed Options in any quarter, then all remaining Options are forfeited. One-eighth of the Options will become exercisable each quarter (each, a "Quarterly Tranche"). The Committed Options are exercisable over a two-day period in the applicable quarter (the "Exercise Period"); provided that if the Exercise Period for a Quarterly Tranche occurs during a blackout period, then such Exercise Period shall instead be the next quarterly Exercise Period.

restricted stock units financial
"Includes 18,852 shares of Class A Common Stock subject to restricted stock units and performance stock units that remain subject to vesting."
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
performance stock units financial
"Includes 18,852 shares of Class A Common Stock subject to restricted stock units and performance stock units that remain subject to vesting."
Performance stock units are a type of company award that grants employees shares of stock only if certain performance goals are met. They motivate employees to work toward specific company achievements, aligning their interests with those of shareholders. For investors, they can influence a company's future stock supply and reflect management’s confidence in reaching key targets.
stock options financial
"Represent stock options to purchase shares of the Issuer's Class A Common Stock ("Options") granted on July 29, 2025."
Stock options are agreements that give a person the right to buy or sell a company's stock at a specific price within a certain time frame. They are often used as a reward or incentive, similar to a coupon that can be used later if the stock price rises, allowing the holder to make a profit.
Quarterly Tranche financial
"One-eighth of the Options will become exercisable each quarter (each, a "Quarterly Tranche")."
blackout period financial
"provided that if the Exercise Period for a Quarterly Tranche occurs during a blackout period, then such Exercise Period shall instead be the next quarterly Exercise Period."
A blackout period is a temporary window when company insiders, employees or certain plan participants are barred from buying or selling the company’s stock, usually around earnings releases or other material events. It matters to investors because it reduces the risk of unfair trading based on secret information and can affect share liquidity and timing—think of it as a “no trading” zone set to keep the market fair and orderly.
